in the invention, during the patient's strong inhalation, because the air inlet pipe 123 is mainly made of silica gel, the outer side surface is smooth and easy to slide in the patient's mouth, and during the patient's inhalation, the outer fixed wall 245 is pressed by the lips to extend and deform outwards, and after being deformed to a certain position, the outer fixed wall 245 is fixed by the inner fixture block 244, along with pressing the auxiliary block 242, the pressure plate 422 is pressed by the pressure guide plate 421, the middle end part of the mounting block 423 is formed into a hole shape, the width of the two end parts of the pressure plate 422 is larger than that of the middle end, and the two end parts are fixedly installed at the inner upper end part of the mounting block 423, and through the downward pressing of the width of the middle end of the pressure plate 422, along with the fixing of the two sides of the pressure plate 422, the pressure guide plate 421 is deformed along with the pressing, so as to keep attached to the patient's mouth part, and fixed by the side fixing plate 424 outside the mounting block 423, the elastic plate a2 is distributed and installed at the upper end of the force guide wall a1 on the inner side of the side surface through three fixing points, so that the force guide wall a1 enables the part of the elastic plate a2 to be pressed and deformed through different pressing points when being pressed, the outer side surface of the force guide wall a1 is attached to the face of a patient, and the stability of the anti-skid side block 124 when the patient inhales is improved.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
